I have a Shuttle SN68SG2 with 4GB of RAM and a AMD Athlon 64 X2 5200+ Socket AM2 2.7GHz Energy Efficient L2 1MB main processor and loaded with XP proffessional. The pc worked quite well for the last 3 years barring a lit issue with booting up in the morning which seems to come from the power supply. Lately the PC has become unusable as it crashes frequently without even a sign of problem no BSOD and it dies stone dead and does not reboot until I press the big button. I have tried all the items I can think of as well as the items given in the forums these include cleaning the debris, all the latest drivers defrag changing the page file checking the ram. The PC will run continuously in safe mode without any problems and it does not record any minidumps when it dies. I suspect the power supply does anybody have any other ideas?
